Most recent maps and atlases show between Magadan Region
and Chukotka the same tipe of boundary lines as between any other two normal subjects,
while the border lines between, say, Koryakia and
Kamchatka are different. This is so in the following sources
I have at hand:

In 1990 this region
unilaterally upgraded itself to an
Autonomous Republic.Stuart Notholt

Description of the flag

It consists of a 1:2 azure field, with a 1:1 white triangle in the hoist
(i.e., this triangle is defined by the intersection of the flag’s diagonal
lines), charged with a roundel of the russian flag
fimbriated yellow.

The height of each "russian" stripe,

the width of the roundel fimbriation and

the minimum distance between the roundel and the triangle’s edge

are equal.António Martins, 21 May 1997

The flag of Chukotka in Russia marks its loyalty, and its
geographical character. The flag is symbolically blue, standing for
the water surrounding Chukotka and its rivers. It also stands for
the Chukchi people, as their national colour is blue. The white in
the hoist is representative of the ice, and snow, covering Chukotka
for most of the year. And to prove the region as a part of Russia,
this design includes the simplified version of the region coat
of arms, that has the Russian flag in the center surrounded by yellow,
and it being in a circle, indicating sun, hope and friendship.Muhamed Mesic, 16 Nov 1998

Wrangel Islandострова

I noticed that Wrangel Island has it’s own
postal issues. Has this
island any form of autonomy and consequently flag?Jaume Ollé, 06 Aug 1999

No. Wrangell Island (острова
Врангеля) is part of
Chukotka. Those stamps are issued by the Russian Postal authorities in Moscow
and sold to in a few central post offices. The closest to Wrangel Island that
those postage stamps ever get is in the album of japanese or alaskan
philatelists… There may be a flag for Wrangell island (rather the flag
of the local town — although I doubt it),
but it would have nothing to do with those postage stamps.António Martins, 07 Aug 1999
